Research Interests
Inflammatory and immune disorders are major public health concerns and novel non-invasive approaches are needed for disease diagnosis, monitoring and accelerating new therapeutics testing. Positron Emission Tomography (PET) imaging of metabolic activity has been used extensively in cancer diagnosis and evaluation, with more than 3 million PET scans administered in clinical centers worldwide in 2005. However, PET applications in autoimmunity, inflammation and monitoring cancer immunotherapy have been limited. Our current research is directed in several areas: (i) development of novel PET probes to image T lymphocyte activation and inflammation; (ii), evaluation of cancer immunotherapy using PET reporter gene approaches; (iii), development of non-immunogenic PET reporter gene systems.
